I abandoned the system. Support was horrible. I tried 2 different board manufacturers that NCH suggested. Neither "helped" the problem, although synway was much better with support and such. All in all - I lost about 4,000 dollars on it. I spent the extra money and moved to Audioworxs and brooktrout cards.
My problems included limited customizability, false key presses (constantly), and the system kicks everyone off when you add a user.. so that makes it good for about 1 user.
